Title: Improvements in or relating to the separation of intermixed divided materials
IPC: B03B4/00
Filed: 1928-12-31
Abstract: 328,663. Peale, R., and Peale, R. Dec. 18, 1928, [Convention date]. Pneumatic separating. - Relates to the separation of mixed materials of different density, such as a mixture of coal and rock, by passing them over. an air pervious table provided with separating riffles and simultaneously subjecting them to a shaking movement and an upward air pressure and consists (1) in the combination of means for producing a pulsating air pressure with a table which has zones of different degrees of perviousness and (ii) in the provision of means for producing air pulsations which are out of phase and vary between different limits at different parts of the table. The apparatus described is of the general type described in Specifications 290,276 and 292,495. The surface of the table 10, Fig. 5, is divided into zones A - - D in which the air perviousness is varied preferably in a progressively diminishing degree in the forward direction, the boundaries of the zones being substantially parallel to the separating partitions 55. In addition, the underside of the table may be provided with a series of small chambers formed by partitions 111, 117, Fig. 9, and a perforated bottom 119, the perforations 120 of which may be closed by stoppers 121 to further grade the air-perviousness of the table according to requirements. The main air-chamber 29, Fig. 1, is fitted with a rotary shutter valve 70, carried by a shaft 71 adapted to be mounted in one of the series of bearing bosses 72 provided in the sides of the air chamber. The valve consists of two fixed plates 80, 81, Fig. 3, and slidably adjustable wings 83, 84, for the purpose of accommodating the valve to the varying depths of the air chamber and also for controlling the upper and lower limits of the pulsating pressures. Adjustment of the shutter valve longitudinally of the air chamber determines different areas of the table in which the. pulsations are out of phase and have different pressure limits. The table is supported on a stationary frame 27 by inclined links 21 and is driven by an eccentric rod 45 and cushioned by buffer springs 52. The frame 27 is pivoted at 40 and adjusted in inclination, by screw rods 41. The construction of the table and the discharging devices are as described in Specification 292,495.

Penetration may be effected by pressing between platens 4, 5 to a depth determined by stops 6, preferably such that the layers do not penetrate fully. The combined layers may be covered by surface panels 7, 8, Fig. 2, secured by adhesive which collects as at 9 around the edges of the honeycomb cells. The honeycomb layers may be formed of resinated paper or one layer may be so formed, the other being of stainless steel. The layers may have cells of different sizes and they, or the layer 3, may consist of two or more parts laid side by side.
